Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662728, here are decompositions:

71 + 8662657 = 8662728
79 + 8662649 = 8662728
131 + 8662597 = 8662728
149 + 8662579 = 8662728
197 + 8662531 = 8662728
211 + 8662517 = 8662728
241 + 8662487 = 8662728
257 + 8662471 = 8662728

Showing the first eight; more decompositions exist.
